How Many Perl, PHP, Python and Ruby Developers Are There ?

Davey Shafik posted recently a very interesting article making the case for PHP. It’s not about comparing programming languages capabilities, but especially concerning access to people and market penetration. Davey pointed to an old post that gives an estimation of Perl, Php, Python and Ruby Programmers availability according to most popular search engines. I updated the estimation so we can have most accurate results. The table below illustrates the results found, I have just truncated Bing results to 1M to have more readable chart, after all I don’t believe there are 50M resumes indexed by Microsoft – and that’s another topic.
